The catch of the day, especially for geekdom, is the SyFy Channel’s live broadcast from Comic Con at 11 p.m. No doubt many attendees this year are still talking about the weekend’s announcement that the 13th Doctor Who will be played by actress Jodie Whittaker, who has starred for three seasons in BBC America’s “Broadchurch” series.

The late George Best, a professional footballer from Northern Ireland, is the subject of an ESPN “30 for 30” special at 8 p.m., “George Best: All By Himself.”

HGTV premieres “Flip or Flop: Atlanta,” with an episode called “Big Money in Buckhead,” at 9 p.m.

Season three of “Growing Up Hip-Hop” kicks off at 9 p.m. on WE.

This week’s “How It’s Made” show on the Science Channel tells us how such things as wood utensils, refrigeration units and moccasins are made. 9:30 p.m.

The second season of “Bad Blood” opens at 10 p.m. on the ID channel.

“Sugar and Spice But Not so Nice” is the title of the third-season premiere of “Beat Bobby Flay” at 10 p.m. on the Food Network.

FRIDAY

“Ozark” is not always an easy show to watch. The cast is terrific in the 10-episode drama available on Netflix today, but you’ll search almost in vain for someone to like among the characters. The series is about a money manager who has been laundering money for a drug cartel. He takes his wife and two kids from Chicago to Lake of the Ozarks to set up a money-laundering scheme to avoid getting offed by the head of the cartel for skimming money. The cast includes Jason Bateman, Laura Linney and Esai Morales.

Also from Netflix today: The complete second season of “Last Chance U,” the first season of “Niko and the Sword of Light” and the first season of “The Worst Witch.”

A new episode of “Big Brother” airs at 8 p.m., a special night, on CBS.

Reelz airs “Amy Winehouse: The Legacy,” a one-hour special at 8 p.m. spotlighting the extraordinary talent of the late singer.

You’ll have to work very, very hard to avoid “The Descendents 2,” the sequel to the ginormous 2015 Disney Channel hit, “The Descendants,” which drew more than 12 million viewers (or 24 million eyes) to screens. All those eyes have been waiting for the sequel, and now it’s here. The new film, also directed by Kenny Ortega, airs at 8 p.m. on ABC, the Disney Channel, Disney XD, Lifetime, Lifetime Movie Channel and Freeform. Just a guess, but I think Disney has a hit on its three-fingered hands.

The film should provide a healthy lead-in to the premiere of Raven-Symoné’s return with a sequel to “That’s So Raven.” The new show, “Raven’s Home,” evokes the concept of the “Full House” sequel, “FullerHouse,” by having Raven and Chelsea Daniels (Anneliese van der Pol) play divorced moms sharing a house and raising their kids together. The new show airs at 10 p.m. and will be followed at 10:30 by “Descendants 2 After-Party.”

HBO airs a new episode of the edgy docu-news series “Vice,” called “A World in Disarray” at 10 p.m.

Dekkoo, the subscription streaming service with content designed for gay men, unveils the sitcom “Stray” today, about an outgoing young gay man and a nerdy straight dude who reunite a few years after college to talk about sex and relationships. Go to www.dekkoo.com for info.

CNN airs the one-hour special “After O.J.: The Fuhrman Tapes Revealed,” featuring CNN correspondent Kyra Phillips interviewing two women who haven’t spoken publicly before about their role in the O.J. Simpson trial, the screenwriter who recorded former L.A. detective Mark Fuhrman and a former cop who worked with Fuhrman.

The SyFy Channel continues its “Live From Comic Con” coverage at 11 p.m.

SATURDAY

The catch of the day is “Risk,” a documentary produced by Sam Esmail, producer of “Mr. Robot,” and airing on Showtime at 9 p.m. Director Laura Poitras spent six years looking at Julian Assange and WikiLeaks, including during the 2016 presidential election.

Season four of “Cold Justice” kicks off at 8 p.m. on Oxygen, the fourth season of Reelz’s “Autopsy: The Last Hours of…” ends at 9 p.m. with an episode about Anissa Jones, who played Buffy on the old sitcom “Family Affair,” and the second season of “The Dude Perfect Show” begins on Nickelodeon at 9 p.m.

“Gone: The Forgotten Women of Ohio” is a new docuseries on Spike, airing at 9 p.m. The series is directed by Oscar-nominee Joe Berlinger, who made the “Paradise Lost” trilogy.

CNN’s second-season release of “Declassified: Untold Stories of American Spies” at 9 p.m. couldn’t be more timely. The eight-parter takes viewers into the secret world of the spy game, with Mike Rogers hosting. Tonight’s episode, “Spies Next Door: Operation Ghost Stories,” is about Russian agents living in deep cover in the U.S.

Nat Geo Wild’s “Fest” launches with “Shark vs. Predator” at 8 p.m., looking at animals who have the nerve to take on sharks.

Then Discovery counters by enlisting none other than Olympian Michael Phelps in the 70-minute “Phelps Vs. Shark” at 8 p.m. and follows at 9:10 p.m. with “Shark-Croc Showdown.” I don’t think that refers to ugly footwear. At 10:10, Discovery airs “The Great Hammerhead Invasion.” Discovery’s evening comes to a comic conclusion at 11:10 with the fifth season opening of “Shark After Dark” with Tony Hale and Joe Romeiro.

In non-fin programming, Issa Rae returns with the second season of her terrific show “Insecure” at 10:30 p.m. on HBO, right after the third-season start of “Ballers” at 10.

Oxygen premieres “The Jury Speaks” at 9 p.m., with an episode about the O.J. Simpson trial.

“Tyler Perry’s For Better or Worse” packs it in for good on OWN at 10 p.m. after six seasons.

Don’t worry: Perry just inked a huge deal with Viacom to develop new shows for BET and other platforms.

And the SyFy Channel continues broadcasting “Live From Comic-Con” at 11 p.m.
